Comprehensive Data Capture When used with Nonin nVision software, users can review trended SpO2 and heart rate data instantly- including the ability to edit parameters for event identification PureSAT Technology Clinically proven PureSAT technology uses intelligent pulse-by-pulse filtering to provide precise oximetry measurements User Friendly Display A variety of indicators ensure reliable reading: a color coded pulse strength bar graph, pulse quality indicator, and sensor fault indicator Power Options Operates on AC line voltage or an internal battery that provides 12 runtime with a 4 hour quick recharge Easy to Read Bright LED displays and large screen allows easy reading, even from across the room Versatile & Capable Adaptable from acute care to home care and neonates to adults; specified for use in motion and low perfusion Internal Memory Records up to 115 hours of data - ideal for extended monitoring User Friendly 3 distinct icons offer helpful indications of signal status Flexible Alarms Includes patient security mode and user-defined default that offers customizable patient settings.
Key tips
- ·A no-signal/flatline alarm gets checked on the patient first, not the monitor - rule out a real clinical event before troubleshooting.
- ·Recalibrate NIBP against a reference manometer, not just a self-test pass.
- ·Reused patient cables (SpO2, ECG leads) are a common source of intermittent-fault complaints - swap the cable before the module.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
No SpO2 / pulse reading or poor signal
HighSymptoms: No saturation / pulse value, "pulse search", low signal quality, implausible values.
Root cause: Worn or wrong SpO2 sensor, a damaged cable, poor site / perfusion, or motion.
Sensor / cable connector fault
MediumSymptoms: Reading drops when the cable is moved, sensor not recognised.
Root cause: Broken conductors in the sensor / extension cable, or a worn connector.
Inaccurate SpO2 vs a co-oximeter
MediumSymptoms: SpO2 consistently biased vs an arterial reference.
Root cause: Sensor degradation, or a monitor calibration / module fault.
Alarm / audio fault
MediumSymptoms: No or quiet audible alarm.
Root cause: Speaker or audio-board fault - a safety-critical failure.
Battery / power fault
MediumSymptoms: Short battery run time, will not power on.
Root cause: Aged battery.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Routine cable and lead-wire inspection for fraying/wear
- ·Battery conditioning cycle
- ·NIBP calibration check against a reference manometer
- ·ECG / SpO2 accuracy verification against a patient simulator
- ·Annual electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: No SpO2 / pulse reading or poor signal
- Fit a fresh, correct-size sensor on a warm, well-perfused, still site.
- Swap the SpO2 extension cable.
- Confirm the pleth / signal-quality indicator improves.
- Test the monitor with an SpO2 simulator across several saturations.
- Replace the sensor / cable, or refer the SpO2 module if the simulator also fails.
Symptom: Reading drops when the cable is moved / sensor not recognised
- Flex the sensor and extension cable along their length while watching the trace.
- Inspect the connectors for damage and clean them.
- Try a known-good cable and sensor.
- Confirm the sensor type matches the module.
- Replace the cable; refer the module connector if it persists.
Symptom: SpO2 biased vs a co-oximeter / accuracy concern
- Compare to an arterial co-oximetry result where clinically indicated.
- Try a known-good sensor of the correct type.
- Verify against an SpO2 simulator at 80 / 90 / 97 %.
- Check the module software / calibration revision.
- Refer the module for calibration if it fails the simulator.
Symptom: No or quiet audible alarm
- Confirm alarm volume is not set to minimum and alarms are not paused.
- Trigger a test alarm (remove the sensor) and listen.
- Check the speaker and its connector.
- Replace the speaker / audio board - a failed alarm is a safety fault.
- Verify the alarm at the set volume before returning to service.
